FILLING-FEELER FOR LOOMS.

Specification of Letters Patent. Patented Aug. 30, 1910.

Application filed March 28,1916. SerialNo. 552,059.

haustion of the working filling.

Looms of this type are technically termed feeler looms because of the instrumentality which intermittingly cooperates 'with and feels the filling in the running shuttle, such instrumentality so controlling the filling-replenishing mechanism as to bring about its actuation when the desired or predetermined exhaustion of the filling in the shuttle occurs.

Various feeler or filling-exhaustion-ii1dieating mechanisms have been devised to ac complish the results desired, and the most successful and extensively used devices of this character are arranged to cooperate or act in conjunction with a preliminary winding or bunch of yarn laid upon the barrel of the filling-carrier before the main or service winding is laid. In order to provide fillingcarriers with such preliminary winding or bunch it is necessary to equip the spinning frame with a special form of builder-motion.

My present invention has for its object the production of .a simple and effective feeler instrumentality which is not dependent for its operation upon the presence of a preliminary winding or bunch of yarn on the filling-carrie,r, and thus filling-carriers can be TlSOCl upori which the yarn has been spun in the ordinary manner on spinning frames of usual construction.

The various novel features of my invention will be fully described in the subjoincd specification and particularly pointed out in the following claims.

Figure tie a top plan View of the filling feeder mechanism of a loom embodying my present invention, with part. of a shuttle and the filling-carrier or bobbin therein, such a substantial quantity of filling being shown as will prevent the functional operation of the feeler; Fig. 2 is a left-hand side elevation of the major portion of the feeler mechanism shown in Fig. 1, with the filling-carrier in crosssection, .but with the filling thereon substantially exhausted so that the feeler is in readiness to perform its functions; Fig. 3 is a view similar to Fig. 2 but with portions in sect-ion and with the feeler in the condition'illustrated in Fig. 1; Fig. 4:

'isa detail in plan showing the filling very near its predetermined oint of exhaustion, almost ready to cause t e functional opera tion of the feeler; Fig. 5 is a perspective view of the part or member of the feeler which never impinges on the filling.

In Fig. 1, A is a shuttle'of suitable character, provided with usual holding jaws B to grasp the ringed head of the removable filling-carrier or bobbin C, the latter having a substantially cylindrical barrel D adjacent the head E. The front wall of the shuttle has a slot at through which the feeler device may enter, in usual manner, and in practice the front wall of the shuttle-box (not shown) has an aperture with which the slot (4 registers when the shuttle is boxed at the feeling side of the loom, all as is usual in well known feeler looms. The outer end of a transmitter F is shown in Fig. 1, having a forwardly extended part G provided in practice with a cam-slot through which is extended a controller H, such parts being substantially like the corresponding parts in United States Patent No. 789,471, granted May 9, 1905 to Wood and Northrop. Through such parts the action of the feeler mechanism is transmitted to effect the desired change in the loom operation.

Herein it will be understood that the actuation of the transmitter F is arranged. to bring about filling replenishment, and as the replenishing mechanism is well known in the art it is not illustrated herein, but it may be of the well known Northrop type, one embodiment of which is shown in patent to Northrop No. 686,903 dated November 19, 1901'.

The free end of the controller H is beveled, Figs. 9. and 3, to insure certainty of full engagement thereof at times with an actuator, to be described. to eficct forward movement of the controller and the resultant rocking of the transmitter F on its fulcrum. in well known manner.

I have herein shown a clmmbcrcd stand or support 'I which in practice is mounted tured to receive the rear end of a hunter' on a fixed part of the loom opposite the adapted to receive outer side and provided with a longitudinal guide-way (S in which is slidably mounted the governor, as it is herein termed, said governor being made as a straight, flat bar I having at its rear end a contact face 8, the front end of the governor being upturned and extended transversely at 9 across the feeler and above the same.

The transverse rear edge 10 of the feeler constitutes its contact face, more or less of which intermifttingly contacts with the filling mass J, Fig. l, on the carrier until substantial exhaustion thereof, and during such period of intermittent filling engagement of the feeler the contact face 8 of the governor is projected a slight distance beyond the face 10, as in Fig. 1. This contact face 8 of the governor is in the path of movement of the exposed part 1) of the barrel of the lilling-carrier, but it is withheld from engagement therewith so long as sutlicient filling remains on the carrier to contact with the face 10 of the feeler. Thus the governor, while movable relatively to the feeler, remains quiescent thereon and moves back and forth in unison with it as the feeler reciprocates in its stand or support I on every alternate beat of the lay untiljsubstantial exhaustion of the filling.

Referring to Fig. t the remaining filling J is so reduced in quantity that the contact face of the governor 7 touches the exposed part I) of the carrier barrel when the contact face of feeler 2 touches the filling, and on the next feeling pick, say, the further diniii'iution of the. filling permits the governor to contact first with the barrel D. 'lhereupon the governor is moved forward upon the feeler and this movement is transmitted to an actuator, to position the latter for engagen'ient with the controller II as the feeler and governor move forward while the lay heats up.

flhe'actuator herein shown as a forwardly extended arm 1]. notched atits front end at 12 and bent down at its rear end, at to join a hub 1- between the ears 4 on tl carrier and fulcruuicd on a transverse pin 1.5. clearly shown in 2 and 3. "in upturned lug it on the hub is apershown as a threaded stud 17 which is screwed into a hole in the bend 13 of. the actuator, and held in longitudinally adjusted position by a cheek-nut 18, the rear 1 of 'a reciprocating feeler end of said hunter. contacting with the part 9 of the governor.

A plunger 19, Fig. 3, elevated by a light spring 20, engages the actuator and nor mally maintains its front end lifted and in inoperative position, shown in Fig. 3, said plunger being mounted on the support I, but permitting sliding movement of the actuator thereupon as the feeler reciprocates under normal. conditions. At such time the notched end 12 of the actuator travels above the beveled end of the controller H, as will be obvious, and the hunter acting upon the governor maintains its contact face 8 pr0- jected the proper distance beyond the contact face it) of the feeler 2.

When the filling is woven ofi far enough to permit the governor to contact with the filling-carrier and be moved forward on the feeler the part 9 of the governor presses upon the hunter 17 and rocks the actuator ll into operative posit-ion, Fig. 2, depressing its notched end 12 so that it engages with the controller H and moves it as the feeler and governor move forward. Such operation of the controller rocks the transmitter F in usual manner and thereplenishing mechanism of the loom is caused to efiect a replenishment of filling in the shuttle, all in the manner common to the Northrop type of loom. I

By adjusting the hunter 1'1 the relative normal position of the contact faces 8 and 10 of the governor and the feeler are varied according to the amount of filling whlch is to remain. on the filling-carrier when the functionalv operation of the feeler mech.

anism is performed. That is to say, the closer thecontact faces are brought into alinementthe less the amount of filling'on the carrier when the functions of the feeler mechanism are performed, and conversely, the greater the projection of the face 8 beyond the face 10 of the feeler the more filling will remain when the governor operates. Thus a most delicate, accurate and effective adjustl'i'ient can be made, for filling of various degrees of fineness, or for the amount of filling which is to remain on the carrier when filling. replenishn'lent is to be effected.

The construction of the mechanism is simple, strong and durable, there are very few parts, and the operation of such mcchanism. depends upon the difference in level between the residue of filling on the fillingcarrier and the bare portion of the carrier barrel adjacent the base of the filling mass, and no preliminary Winding 0r bunch of filling is required.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. An automatic filling-replenishing loom having, in combination, a shuttle equipped with a filling-carrier having its barrel al- Z ator.
